Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Synodic month length 29.71 days

Length of current 1126 lunation is 29 days, 17 hours and 7 minutes. It is 1 hour shorter than next lunation 1127 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 23 minutes longer than the mean length of synodic month, but it is still 2 hours and 40 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠102°

This New Moon true anomaly is ∠102°. At beginning of next synodic month true anomaly will be ∠137.9°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

2 days after point of apogee on 25 January 2091 at 14:57 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 6 February 2091 at 09:12 in ♍ Virgo.

Distance to Moon 400 776 km

Moon is 400 776 km (249 031 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 363 106 km (225 624 mi).

Moon after descending node

5 days after its descending node on 23 January 2091 at 02:24 in ♓ Pisces, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 5 February 2091 at 23:52 in ♍ Virgo.

Moon before northern standstill

10 days after previous South standstill on 17 January 2091 at 18:01 in ♐ Sagittarius, when Moon has reached southern declination of ∠-18.589°. Next 3 days the lunar orbit moves northward to face North declination of ∠18.537° in the next northern standstill on 1 February 2091 at 06:49 in ♋ Cancer.

Syzygy in 6 days

After 6 days on 4 February 2091 at 04:46 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
